The V1 body armour was made by enchanting rune armour, the inside being made of clockwork mechanisms. The joints were wooden, and most of the belts, weapon straps and joint coverings were made of leather. The mind mechanism was used by infusing an imp's brain inside a wire shell. This worked initially, the ZTI's knowledge of biology helping to tame the imps. The rebellion came when the imps took control and started destroying the base.
